I know this from wiring money to wm-center.com and wondered why the WU agent didn't ask me for the city. As for the secret question that's basically vanished, everybody has to present ID now in almost every country. Often, you don't have to use western union. There are a ton of alternatives like contact-sys, migom, ria, marco polo and anelik. All of these Eastern European, Russian and UK transfer services have offices in whatever country you live in to send money. Use them if WU gives you bullshit trouble for picking up too many transfers or sending too much.
Regarding that, we shouldn't.
We had a girl start coming in and picking up like four or five receives a day from different parts of the country. They were only small receives from 50-150 bucks a pop, but we still thought it was suspicious.
We consulted the auditor-man about it and he arrived at the same conclusion as us. It seems suspicious but we couldn't really think of any scenario where receiving lots of small amounts could be used to (effectively) launder money or take drug profits (considering they were coming from different places). So we continue to do them for her.
My working theory would be that she's a cam whore but half of her receives come from her mom, so she's probably just someone from a money having family. But yea as long as you aren't receiving thousands at a time you're ok on that...
EDIT: I wanted to come back here and admit that I was wrong.
I went to work and found out for damn sure.
Under 1000 bucks and you CAN receive without an ID with only a test question.
